Submitting order crashes sometimes

[andrzejkrzywda]

According to our tracker (honeybadger) we get NoMethodError: undefined method uid' for nil:NilClass` sometimes.

It seems to come from orders/show action. On further investigation it comes after we redirect to show from the create action.

The create action creates 2 commands, which then result in events, which then are handled by read models.

It's very likely that after the recent switch to async event handlers, now this not often executes on time.

We'd need to fix this somehow.
